Abstract: This paper researches and analyzes the operation content and contact methods of station duty personnel and field duty personnel, and designs a GSM-R based notification field service solution by combining the current situation of train operation equipment. This solution proposes the concept of automatic notification to field duty personnel by referring to the design concept of wireless route prediction application technology in the CTC system,  and studies the timing and conditions of automatic notification to field duty personnel. Portable wireless handheld terminals with human-computer interaction for field duty personnel are set. Difficult implementation and poor application effect of the current notification field function are solved by using the existing GSM-R wireless communication channel to interact information so as to improve the management technology and automation level of train service personnel's receiving and departure operations again.

Key words: notification to field duty personnel, handheld terminal, field duty personnel, Global System for Mobile Communications-Railway (GSM-R)

摘要： 调研分析车站值班员与外勤值班员的作业内容和联络方式，结合行车设备现状，研究设计一种基于GSM-R的通知外勤方案。借鉴调度指挥系统无线进路预告应用技术的设计思路，提出自动通知外勤的理念，研究自动通知外勤的时机与条件。为外勤值班员设置具备人机交互的便携式无线手持终端，利用既有的GSM-R无线通信通道交互信息，解决目前通知外勤功能实施难度大、应用效果差的问题，再次提升车务人员接发车作业的管理技术与自动化水平。
